YAllfFRE), OF DETROIT, MICHIGAN i ANCHORAGE MEANS FOR TRACK RAILS AND THE LIKE Appneanon sied June so, leso. serial No. 465,039.

This invention relates generally to means for fastening or anchoring track rails upon suitable supports. i

One of the essential objects of the inventionis to provide simple and eiiicient means "ab rails will be held tightly upon their supports.

Other objects, advantages, and novel details of construction of this invention will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings,

wherein:

Figure 1 is a cross sectional View through a concrete roadbed and showing rail anchorage means embodying my invention applied 3c thereto;

Figure 2 is an enlarged fragmentary vertical sectional view through the roadbed and one of the rails; y

Figure 3 is an elevation of one of the stirrup sections;

Figure 4 is a detail view of one of the clamping members;

Figure 5 is a view taken at right angles to Figure 4;

Figure 6 is a view similar to Figure 2 and showing a slight modification.

Referring now to the drawing, 1 is a roadbed; 2 and 2 respectively are laterally spaced rails on the bed; 3 are boards set in the bed beneath the rails; 4 and 5 respectively are stirrup sections embedded in the concrete upon opposite sides of the rails and having inwardly inclined portions 6 and 7 respectively above the concrete provided with threaded openings 8 and 9 respectively; 10

and 11 respectively are steel castings adapted to be clamped upon the bases 12 of the rails; and 13 and `14 respectively are set screws threadedly engaging the openings 8 and 9 in the inclined portions 6 and 7 respectively of the stirrup sections and constituting followers for the castings and 1 1 so that the rail bases 12 may be clampedvupon the bed 1. As shown, the castings 10 and 11 are identical in construction. Each preferably has a transversely extending substantially L-shaped recess 15 in one side and is provided in its other side with a longitudinally extending channel shaped recess 16. l/Vhen assembled the long sides 17 of the L recesses 15 incline down wardly and outwardly and engage the inclined top faces 18 of the rail bases, While the short sides 19 of said recesses are vertically disposed and engage opposite edges Vof the rail bases. The channels'l are inclined relative to the bed and receive the inner ends of the screws 13 and 14. In fact, the bases 2O and 21 respectively of the channels are substantially parallel to the inclined portions 6 and 7; hence are at right angles to and provide firm bearings or abutments for the screws 13and14..V i i With this construction the screws l13 and 14 maybe loosened to permit both lateral and vertical adjustments of the rails 2 relative to the `bed'l and maybeeasily and quickly tightened to hold the rails in adjusted position on the bed. r `In the present instance .wedges 22 are pro- ,videdto take up play between the screws and castings. For, insta-nce, when a load such as a train ison the, rails, theV bases 12 and castings 10 and 11 move downwardly slightly rela-tive to the screws rk13 and 14., Thus spaces are momentarily provided between the bases 20 and 2,1 ofthe recesses 16 and the inner ends ofthe screws 13 and '14, and successive moveymentsof the nrails aud'castings 10 and 1 1 in this manner would have a. tendency to loosen theconnections. Hence, the wedges 2,2 are usedV to take up such play. In use these "down by gravity-in the recesses when spaces are provided therefor as a result of loads being placed upon the rails. Thus the wedges automatically maintain tight connections between the parts.

In Figure 6 I have illustrated a slight modification in which the stirrup sections and 3l are integral. Otherwise the construction is the same as that illustrated in Figures l to 6 inclusive.

While it is believed that from the fore going description the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do Vnot limit myself to what is herein shown and described and that such changes may beresorted to when desired as fall within the scope of `what is claimed.

That I claim as my invention is l. The combination with a rail of a track, and a support therefor, of means for anchoring the rail upon the support, including' clamping members engaging opposite edges of the .base of the rail. anchorage members rigid withthe support upon opposite sides of the rail, and followers for said clamping members carried by said anchorage members.

2. Means for anchoring a rail of a track upon a suitable support including a stirrup section adapted to be secured to the support and having an inclined portion, a screw threadedly engaging the inclined portion, and a clamping memberfree with respect to the screw and having slots respectively receiving a portion of the rail and an end of the screw.

Means for anchoring a rail of a track upon a suitable support including a casting having a slot for ,receiving an edge of a rail and having another slot, a member attachable tothe support -having an inclined por tion substantiallyparallel'to the base of the second-mentioned slot, and a set screw extending through the inclined portion and having the end thereof engageable with the base of the second-mentioned slot in the casting. l

4. The combination with a concrete roadbed and a rail on said bed, of means for securing the rail upon the bed including a member embedded in the bed and provided above the bed with an inclined portion, a clamping member having portions engaging the top face and an edge of the rail base, and a follower for the clamping member adjustable in the inclined portion aforesaid of said member.

5. Means for anchoring a rail of a track upon a suitable support includinga member rigid with the support atone side ofthe rail, a clamping member engaging the rail, a follower for Vt-he clamping member' carried by the first mentioned member, and, means between the follower and last mentioned membefr operable automatically to take up play between vsaid .parts t'oj insure a tight c0111- nection between the clamping member and rail.

6. Mean-s for anchoring a rail of a track upon a suitable support including a clamping member engageable with the base of the rail, a follower for the clamping member, af support for the follower rigid with vthe rail support, and means associated with the clamping member and follower for automati cally'taking up play therebetween toV insure a tight connection between the clamping member and rail.

7. The combination with a concrete roadbed and a rail ou said bed, of means for securing the rail upon the bed including upright members embedded in the bed and provided above the bed with inclined portions,` clamp.- ing members engaging opposite edges of the rail, and followers for said clamping members adjustable transversely ofthe inclined portions of the upright members aforesaid.

8. The combination with a rail of a track, and a support for said rail, of means for anchoring the rail upon the support including upright members rigid with the support and disposed upon opposite sides of the rail, said upright members being provided above the base of the rail with inclined portions, clamping members engaging opposite edges of the base of said rail, followers for the clamping'members adjustable in the i-nclined portions aforesaid, and removable means associatedwith said clamping members and followers for automatically taking up play therebetween to insure tight connections between the clamping members and the rail.

In testimony whereof I'aflix myv signature.

PAULA CHIPMAN.
